To all whom it may concern:

Be it known that l, liner) H; Hansen, a subject of the Emperor of Germany, resident of Pittsburgh, in the county of illegheny and State of Pennsylvania, have invented a new and useful lmprovementin Dump Gars; and I do hereby declare the following to be a full, clear, and exact description thereof. 1

My invention relates to dump cars of tilting body type.

lhe object of my invention is to provide a dump car of this type in which the body of the car in dumping travels outward whereby the body is thrown "farther away from the end frame which permits of a larger dumping angle and at the same time makes it possible to reduce the height of the car which is a great point of'aclvan'tage in the loading of such cars.

In the accompanying drawing Figure l is a side elevation of my improved dump car partly in section; Fig. 2 is an end view partly in section; Fig. 3 is a plan view of the supporting member on the truck.

In the drawing the numeral 2 designates a suitable truck carried by the wheels 3, the truck being of any desired construction and as it forms no part of my invention, it will not be necessary to describe the same in detail.

Riveted or otherwise secured to the truck 2 at suitable intervals are the supporting members 4. These supporting members may be formed of cast steel or other suitable metal, and said members are provided with the central circular recesses 5 extending in direction longitudinal of the truck, and sloping from said recesses 5 are the rocking faces 6. The rocking faces 6 merge into the recesses 7 which are formed in the walls 8 of the supporting member l, and beyond the recesses the inner Walls bulge inwardly as at 9.

The upper supporting members 1% are riveted or otherwise secured to the central sills 11 of the car-body and said upper sup porting member is provided with the se1nicircular bearing 12 which is adapted to en gage the recess 5 in the lower-member 4;. At opposite sides of the bearing 12 are the rocking faces 13 which are adapted in the the dumping of the car to engage the rocking faces 6 of the lower member. The outer edges of the upper member are provided 1 dpplieation February fit, fi lerial File.

with a reunded portion 14 which is adapted to fit in and engage the recesses of. the lower member. The upper member 1'0 is further provided with the recesses 15 which are adapted to lit over and engage the rounded portions 9 of the walls of the lower.

member duiing'the dumping operation.

lhe space or opening termed between the walls oi: lower member is made ust large enough to conveniently receive the up per member, so that when the upper member is in normal position the body of the car may be lifted vertically to be disengaged from the lower member without the removal of any hinge pins, bolts or other parts.

The chains 1% connect the body of the car with the truck to prevent the dumping'ot' the car until the point of dumping has been reached, or during the loading of thecar.

The sides of the car form the doors 1'4" which are opened automatically by suitable lever mecha ism which fin-ms no part oi my oresent invention.

ihe operation of dumping my improved car is as follows: The chain 16 is released and force is applied todump the car in the direction desired. In the first movement or the car in dumping, the turning will be done on the bearings 12 engaging the re ceases 5 and in this way the starting resist ance is readilyovercome, owing to the car turning on a single hinge point. When this starting resistance has been overcome the body will have received a dumping momentum, whereupon the rocking faces 6 and 1S oi the supporting members engage each other and this permits of the outward travel of the body of the car, while at the same time the portions 14 oi the uppertmember enter the recesses 7 of the lower member. In this way the members are interlocked so that it is practically impossible to remove the body from the underframe, this eliminating the possibility of the body accidentally leaving the underiirame, which is a advantage, as the rough usage to which such cars are subjected and the rough tracks on which they are run very often causes the biidy to be thrown oil the underframe. Furthermore as stated above, the engagement of the rocking faces permits the body of the car to in T illitduction in the height of the car is a great advantage'where the cars are loaded byin my invention.

By my invention I combine the advantages of readily overcoming the starting re-,

sistance together with the outward movement of the car which allows a larger dumping angle.

What I claim is: 1. In a dump car, the combinationwith a suitable truck, a supporting member hav ing a central longitudinal hinge recess, downwardly inclined rocking faces at either side thereof and terminating in lateral recesses in the walls of said support, a body, a supporting member connected to said body, a central longitudinal hinge portion on said supporting member engaging said central recess in said lower member to form a hinge connection for initial rocking of the body, saidupper member having up- Wardly inclined rocking faces adaptedto enthe rockin faces of said lower member gacgle an portions a apted to engage within the lateral recesses in the sides of said lower member. 7

2. In a dum car, the combination with a suitable true of a supporting member having a. central hinge recess, downwardly inclined rocking faces at either side thereof and terminatin in lateral recesses having overhanging si e walls, a body, a supporting member connected to said body and having a central hinge portion engaging the bein greater than the outside width across the ateral projections of said upper mem-' ber whereby the car body may first swing on its hinged connection and then move laterally during the dumping operation to (ic liver the load well outside of the running gear of the car.

3. In a dump car, the combination with a suitable truck, of a supporting member having a central hinge recess, downwardly inclined rocking faces at both s1des thereof and terminating 1n recesses havlng overhanging walls, a body, a supporting member connected by. said body'having a centralhinge projection to form a central hinged connection with said central recess in said lower member to form a hinge for initial rocking of the body, said upper member having upwardly -inclined rocking faces adapted to engage the rocking faces of said lower member and having portions adapted to engage beneath the overhanging walls of the recesses in the sides of said lower member and having recesses in its side walls adapted to hinge upon the overhanging side walls of said lower member. 1

In testimony whereof, I, the said KARL H. HANSEN, have hereunto set my hand.
